B)Accurate.
C)Valid.
D)Consistent.

Question 13

With face validity,the validity is not tested statistically.

Question 14

How can content validity of a scale be determined?

A)A panel of experts judges the content validity of an instrument.
B)Different instruments that intend to measure the same concept,are correlated with each other.
C)Two variables that are respected not to correlate with each other,are correlated with each other.
D)Through correlation or regression it is found out to what extent a prediction done on the basis of the instrument really proves to be true.
